Non-Surface Active Polymers -Mechanism of its Specia Characteristics, Nanostructure of their Self-Assembly, and Applications

离子型两亲二嵌段共聚物的非表面活性是我们在世界上首次通过实验发现的，这是不符合表面和界面化学常识的。我们已经澄清了这种独特的性质是由于空气/水界面上的像电荷排斥以及在体溶液中稳定的胶束形成。此外，我们还成功地通过pH和温度等外部因素控制了嵌段聚合物在单体和胶团之间、非表面活性和表面活性之间的转变，这些因素改变了嵌段聚合物的离子性和疏水性平衡。

Non-surface activity of ionic amphiphilic diblock copolymers, which we found experimentally first in the world, is out of common sense of surface and interface chemistry. We have clarified that this unique property is due to image charge repulsion at the air/water interface and also to stable micelle formation in bulk solution. Furthermore, we have succeed to control the transition between unimer and micelle, and between non-surface active and surface active by external factors such as pH and temperature, which change the balance of ionicity and hydrophobicity of block polymers.
